Register your PS3 nickname online even if you can't get a PS3

Sony announced that when the PS3 launches in the US on November 17, that day everyone will be able to register their usernames online at the PlayStation Store via your PC.

This way you'll be able to register your favorite username before either the PS3 is launched in your country or before you're able to get one, as stores are already canceling pre-orders due to lowered shipment numbers.
